BACKGROUND: We aimed at investigating whether the acute abrogation of leptin after bariatric surgery is able to reduce neutrophil activation and potentially affect type 2 diabetes mellitus (T2DM) remission. METHODS: Metabolic and inflammatory parameters (i.e. leptin, IL-6 and neutrophil products) were compared at baseline (before bariatric surgery), one month, one and three years after surgery in morbid obese (MOB) T2DM patients (n=12) and non-MOB controls (n=32)...

Over a relatively short period, obesity and type 2 diabetes have come to represent a large medical and economic burden to global societies. The epidemic rise in the prevalence of obesity has metabolic consequences and is paralleled by an increased occurrence of other diseases, such as diabetes, cancer and cardiovascular complications. Together, obesity and type 2 diabetes constitute one of the more preventable causes of premature death and the identification of novel, safe and effective anti-obesity drugs is of utmost importance...

BACKGROUND AND AIMS: The majority of patients with type 2 diabetes mellitus (T2DM) have obesity. Studies show that bariatric surgery is superior to medical treatment for remission of T2DM. Nevertheless, very few patients undergo surgery, and a less-invasive endoscopic alternative is desirable. METHODS: This was a single-arm first-in-human pilot study, designed to evaluate the technical feasibility, safety, and clinical performance of the incisionless magnetic anastomosis system (IMAS) in creation of a partial jejunal diversion (PJD)...

Type 2 diabetes mellitus (T2DM) is one of the largest health emergencies of the 21st century given the worldwide increase of obesity during the last decades and its close association. T2DM is an inherited, polygenic and chronic disease caused by the interaction between several genetic variants in genes and the environment. The continuous search for new and more effective tools to achieve appropriate glycemic control became imperative in order to reduce long-term complications and mortality rates related to T2DM...

Colchicine is one of the oldest plant-based medicines used to treat gout and one of the most important alkaloid-based antimitotic drugs with anticancer potential, which is commercially extracted from Gloriosa superba. Clinical trials suggest that colchicine medication could prevent atrial fibrillation recurrence after cardiac surgery. In addition, therapeutic colchicine is undergoing clinical trials to treat non-diabetic metabolic syndrome and diabetic nephropathy. However, the industrial-scale biomanufacturing of colchicine have not yet been established...

The term metabolic surgery describes bariatric surgical procedures used primarily to treat type 2 diabetes and related metabolic conditions. Originally, bariatric surgery was used as an alternative weight-loss therapy for patients with severe obesity, but clinical data revealed its metabolic benefits in patients with type 2 diabetes. Metabolic surgery is more effective than lifestyle or medical management in achieving glycemic control, sustained weight loss, and reducing diabetes comorbidities. Perioperative adverse events are similar to other gastrointestinal surgeries...

Iron status is known to be associated with the physiology of adipose tissue (AT). We aimed to investigate AT heme and expression of heme exporter (FLVCR1) in association with obesity and type 2 diabetes (T2D). Substantial amounts of FLVCR1 mRNA and protein levels were detected in AT, being significantly increased in subjects with T2D, and positively correlated with fasting glucose, fasting triglycerides and with circulating markers of iron stores (serum ferritin, blood hemoglobin and hematocrit). In both visceral (VAT) and subcutaneous AT (SAT), increased heme levels were found in subjects with T2D...

To examine the contribution of Non-Esterified Fatty-Acids (NEFA) and incretin to insulin-resistance and diabetes amelioration after malabsorptive metabolic-surgery that dramatically reduces circulating NEFA. In fact, NEFA infusion reduces glucose-stimulated insulin secretion and high-fat diets predict diabetes development. Six healthy-controls, 11 obese and 10 Type-2-Diabetic (T2D) subjects were studied before and 1 month after Bilio-Pancreatic Diversion (BPD). Twenty-four hours plasma glucose, NEFA, insulin, C-peptide, glucagon-like peptide-1 (GLP1) and gastric-inhibitory-polypeptide (GIP) time courses were obtained and analyzed by Granger causality and graph analyses...

BACKGROUND: The latter are inhabited by over 15 million people, i.e. 39.5% of Polish population, including about 5 million rural residents in the Podlaskie voivodeship. The incidence of obesity is associated with increased prevalence of obesity-related conditions. The conducted studies do not confirm the efficacy of conservative treatment obesity, but show that bariatric procedures produce the best long-term results. OBJECTIVES: The aim of the study was to present the effects of bariatric obesity treatment (LAGB, SG, RYGB) on body mass index (BMI), selected diabetes control parameters, dyslipidemia, hepatic and renal enzymes, blood count, and hypertension control...

Background & Aims: TLR9 deletion protects against steatohepatitis due to choline-amino acid depletion and high-fat diet. We measured TLR9 in human NASH livers, and tested whether TLR9 mediates inflammatory recruitment in three murine models of NAFLD. Methods: We assayed TLR mRNA in liver biopsies from bariatric surgery patients. Wildtype (Wt) , appetite-dysregulated Alms1 mutant (foz/foz),Tlr9(-/-), and Tlr9(-/-).foz/foz C57BL6/J mice and bone marrow (BM) chimeras were fed 0.2% cholesterol, high-fat, high sucrose (atherogenic[Ath]) diet or chow, and NAFLD activity score (NAS)/NASH pathology, macrophage/neutrophil infiltration, cytokines/chemokines and cell death markers measured in livers...

The gut hormone incretins have an important physiological role in meal-related insulin release and post-prandial glucose control. In addition to weight loss, the incretin hormones have a role in glucose control after bariatric surgery. The release of incretins, and specifically of glucagon-like peptide (GLP)-1, in response to the ingestion of nutrients, is greatly enhanced after gastric bypass (RYGBP). The rapid transit of food from the gastric pouch to the distal ileum is responsible for the greater GLP-1 release after RYGBP...

Over the past decade, bariatric surgery emerged as the most effective treatment modality for obesity and its complications, especially type 2 diabetes. Initially introduced on the basis of their capacity to restrict food intake and/or induce dietary fat malabsorption, the current bariatric surgery procedures result in many more physiological changes that may also partly explain their potent and sustained anti-obesity and anti-diabetic effects. In the session 2 of the 17th International Symposium of the Université Laval Research Chair in Obesity, outstanding speakers have provided insight into novel clinical and pathophysiological aspects in bariatric surgery...

PURPOSE OF REVIEW: Type 2 diabetes (T2D) is a growing public health problem in youth, but conventional treatments are often insufficient to treat this disease and its comorbidities. We review evidence supporting an emerging role for bariatric surgery as a treatment for adolescent T2D. RECENT FINDINGS: Paralleling what has been seen in adult patients, bariatric surgery dramatically improves glycemic control in patients with T2D. In fact, remission of T2D has been observed in as many as 95-100% of adolescents with diabetes after bariatric surgery, particularly vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) surgery...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) surgery has been shown to induce positive metabolic adaptations for individuals with severe obesity (body mass index ≥40 kg/m(2)), including improved peripheral insulin action. Although a major site of insulin action, the time course changes in skeletal muscle glucose metabolism following RYGB is unclear. OBJECTIVES: To investigate the acute and chronic effects of RYGB surgery on insulin-stimulated glucose metabolism in cultured human primary myotubes derived from nondiabetic severely obese humans...

BACKGROUND & AIMS: Bile acids (BAs) play a key role in lipid uptake and metabolic signalling in different organs including gut, liver, muscle and brown adipose tissue. Portal and peripheral plasma BA concentrations increase after a meal. However, the exact kinetics of postprandial BA metabolism have never been described in great detail. We used a conscious porcine model to investigate postprandial plasma concentrations and transorgan fluxes of BAs, glucose and insulin using the para-aminohippuric acid dilution method...

BACKGROUND: Metabolic surgery is an effective option for treatment of type 2 diabetes. Although body mass index (BMI) has several limitations in differentiating the metabolic risks of the same weight of muscle and fat, it is used as the basis of indication for metabolic surgery. OBJECTIVES: Since visceral fat is highly associated with metabolic disease, we evaluated the effectiveness of visceral fat proportion (VFP) for predicting metabolic risk preoperatively. SETTING: University hospital...
